About Us

The Golf Instruments®Company has a long and distinct history in the design and manufacture of innovative sports equipment. With roots going back to early Southern California car, boat, and dragster racing, three generations of Cooks have designed, invented, and capitalized on California’s fanatical enthusiasm for sports.

Craig Cook, Owner of Golf Instruments®Co., first learned about materials and design from his perfectionist/inventor father, and after graduating from college with an Industrial Arts degree in 1972, began Cook Bros. Racing. The company pioneered. the sport of Bicycle Moto-Cross in Southern California with their Alpine Mountain Bike, which was one of the first mountain bikes in the world. (It is on display in the Mountain Bike Hall of Fame in Crested Butte, Colorado.) Other innovative Cook Bros. Products included sealed bearing BMX hubs and the 7075 billet aluminum crank arm. The company is still a holder of two United States Patents for component designs.

Continuing the tradition, in 1987 Craig started a new company called C.D. Products producing a line of mountain bike frame sets.

When golf became big business, Craig turned his interests in materials and design to golf equipment and started re-manufacturing a popular loft-lie gauge. Soon his new company, Golf Instruments®Co. was producing a complete line of loft-lie gauges in three different styles. Their newest offering is a high-precision, high-tech shaft puller for delicate graphite composite golf club shafts.

Golf Instruments®Co. is a sole proprietorship. The company is constantly working on new and innovative ideas, and is open to others, please send inquires.
